"Governments need to integrate anti-corruption actions into all public decision-making", said Huguette Labelle, chair of Transparency International (TI), a body set up in 1993 to expose and tackle countrywide corruption.

"Priorities include better rules on lobbying and political financing, making public spending and contracting more transparent and making public bodies more accountable to people."

TI believes there are strong correlations between poverty, conflict and perceived levels of corruption.
